Lesson Excerpt

Mental Retardation is defined by a low level of intellectual functioning combined with major difficulties in daily living skills. There are four levels of Mental Retardation: Mild, Moderate, Severe, and Profound. IQ level, also known as intelligence quotient, is a major dividing factor for the different levels of Mental Retardation. IQ level is based on results from intelligence tests.

Mild Mental Retardation

Mild Mental Retardation is applied to people who have an IQ level of 50-55 to about 70. Approximately 85% of individuals with Mental Retardation fall into this category. Those grouped in this category normally develop communication and social skills during ages 0-5. It is often difficult to tell them apart from children who do not have Mental Retardation until they are older.
